i+Dear reader, in this document we will see differents command line	Err	bitreich.org	70
i+software which can be used to connect to a gopher server.	Err	bitreich.org	70
i+	Err	bitreich.org	70
i+	Err	bitreich.org	70
i+Printf + netcat	Err	bitreich.org	70
i+===============	Err	bitreich.org	70
i+	Err	bitreich.org	70
i+It's possible to write request "by hand" using printf to format the	Err	bitreich.org	70
i+request string and then netcat to send it to the remote server.	Err	bitreich.org	70
i+	Err	bitreich.org	70
i+A request of the file "/tutorials/cmdline.txt" will looks like this :	Err	bitreich.org	70
i+	Err	bitreich.org	70
i+    printf "/tutorials/cmdline.txt" | nc somedomain.com 70	Err	bitreich.org	70
i+	Err	bitreich.org	70
i+You will get the server answer directly into your output. Be careful	Err	bitreich.org	70
i+if you ask binary files, it will be displayed on your screen, this is	Err	bitreich.org	70
i+not something a regular user want. If you want to download a binary	Err	bitreich.org	70
i+file, you can redirect the output to a file using ">" or pipe it to	Err	bitreich.org	70
i+another software (or using tee for both at the same time).	Err	bitreich.org	70
i+	Err	bitreich.org	70
i+The following example will download a music file, save it on the	Err	bitreich.org	70
i+filesystem and play it with mpv while downloading.	Err	bitreich.org	70
i+	Err	bitreich.org	70
i+    printf "/some_music.ogg" | tee saved_music.ogg | mpv -	Err	bitreich.org	70
i+	Err	bitreich.org	70
i+You may have seen that the data type is not part of the request	Err	bitreich.org	70
i+string, this is because it is only useful for the client to decide how	Err	bitreich.org	70
i+to handle the content. In the current case, the client is YOU, so if	Err	bitreich.org	70
i+you ask a menu and you want to download a file which has been tagged	Err	bitreich.org	70
i+with type "I" then you should use the right process to deal with an	Err	bitreich.org	70
i+image file.	Err	bitreich.org	70
i+	Err	bitreich.org	70
i+	Err	bitreich.org	70
i+Curl	Err	bitreich.org	70
i+====	Err	bitreich.org	70
i+	Err	bitreich.org	70
i+It is possible to use curl to connect to a gopher server, most of its	Err	bitreich.org	70
i+options are supported, like timeout or traffic shaping. You need to	Err	bitreich.org	70
i+pass a full url with "gopher://" at the start to curl to tell it you	Err	bitreich.org	70
i+want to request a gopher server.	Err	bitreich.org	70
i+	Err	bitreich.org	70
i+By default, curl will output the server result to stdout. Explanations	Err	bitreich.org	70
i+can be found in the previous section about this.	Err	bitreich.org	70
